Application filed August 11, 1887. Serial No. $246,653.

To all whom, it may concern.-

Be it known that we, EVERETT C. ELLWOOD, residing at Greens Farms, in the county of Fairfield and State of Connecticut, and FRANK BATEMAN, residing at Spring Mills, in the county of Camden and State of New Jersey, citizens of the United States, have invented certain new and useful Improvements in Feed- Regulating and Cut-Off Mechanism for Seed- Drills; and we do hereby declare thefollowing to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to simplify the construction of this class of mechanism and improve its operation in use.

With these ends in view we have devised the novel construction and arrangement of parts of which the following description, in connection with the accompanying drawings, is a specification, numbers being used to denote the several parts.

Figure 1 is a longitudinal section of a seeddrill embodying our invention, the cut-otf arm being in the closed position; Fig. 2, a partial plan view, the agitator being removed and the feed-slide moved to the fully-opened position; Fig. 3, a similar view, the feed-slide being in a partially-opened position; Fig. 4, a transverse section of the hopper and seed-eonveyer;

and Fig. 5 is an enlarged detail sectional view of the feed-slide and cut-off arm, the latter being in the opened position.

1 denotes the main wheel; 2, the presserwheel; 3, the side bars; 4, the handle, and 5 the agitator. These parts may all be of the ordinary or any preferred construction. Mechanism for operating the agitator is not shown, as it forms no portion of our present invention.

6 denotes the hopper, which is in form substantially the same as that shown in Patent No. 289,520, dated December 4, 1883.

7 denotes the seed-conveyor, and 8 a share secured thereto by a set-screw. These parts also may be of the ordinary or any preferred construction.

9 denotes the feed-slide, which in the present instance is substantially similar to the (N0 model.)

slide shown in Patent No. 319,211, dated June 2, 1885.

10 denotes a pear shaped seed opening in the bottom of the hopper, and 11 a similarlyshaped seedopening through the feed-slide. The position of the opening through the slide is reversed relatively to that in the bottom of the hopper, so that when the slide is at the fully-opened position, as in Fig. 2, aperfectlyround opening is formed, through which the seed passes from the hopper down into the conveyer. YVhen the slide is moved from this position toward the closed position, as in Fig. 3, the pointed end of the opening through the slide is moved toward the pointed end of the opening in the hopper, so that a diamondshaped opening of any desired size is left, through which the seed passes from the hopper into the conveyer, as is clearly shown in Fig. 3. If preferred, openings 10 and 11 may be made diamond shape instead of pearshape. This is a more detail of construction, not affecting the merits of the invention, which it was not deemed necessary to illustrate in the drawings. The forward end of the slide is guided in an opening, 12, made to receive it in the base of the hopper, as clearly shown in Fig. 4. The rear end of the slide rests upon a cross -piece, 13, the ends of which are secured, respectively, to the side bars. (See Figs. 2 and 3.)

14 denotes a slot in the slide, and 15 a boss upon the upper side of the cross-piece, which passes through the slot, serving as a guide for the slide and also as a center or pivotal point for the cam-plate 16, the functions of which will presently be more fully explained. A bolt, 17, passes up through the cross-piece, the boss, and the cam-plate, and thelatterislocked in place by a thumb-screw, 18, engaging the bolt and bearing upon the top of the camplate.

19 denotes a lug upon the upper side of the feed-slide, one side of which is preferably made angular, one of the angles resting against the edge of the cam-plate, as clearly shown in Fig. 2. This lug is kept in engagement with the cam-plate by means of a spring, 20, upon a rod, 21, under the slide, one end of the spring acting against a lug, 22, on the under side of the slide and the other against a lug, 23, on the under side of the cross-piece. The rear end of rod 21 is secured to lug 22 and its forward end passes through an opening in lug 23, asis clearly shown'in Fig. 5. The cam-plate is solaid out as to have a varying semi-diameter-that is to say, every portion of its edge is at a different distance from the pivotal point than any other portion. It will thus be seen that as the spring acts to hold a lug, 19, in contact with the edge of the cam-plate rotation of the latter must cause forward or backward movement of the feed-slide. Notches are provided at the edge of the cam-plate adapted to register. with lug 19, and the names of various kinds of seed are placed upon the top of the cam-plate in line with their corresponding notches, so that by turning the camplate until the notch corresponding with the seed which it is desired to sow is in line with lug 19 the feed-slide is so adjusted as to leave an opening of suitable size to permit a proper quantity of that class of seed to pass into the conveyer.

It is of course not necessary that the lug should register exactly with any one of the notches, but it may be set at any point be-- tween notches to allow for larger or smaller seed, or a greater or less quantity of any kind of seed. The ease with which this may be done is an important advantage of our present construction.

24 is a finger-piece upon the cam-plate for convenience in operating it. When the feedslide has been adjusted correctly for the kind of seed that it is desired to sow, the cam-plate is locked in the desired position by turning down thumb-screw 18. In order to provide a perfect cut-off for the seed which may be used at all times without disturbing the adjustmentas, for example, in turning at the ends of rows, or in going to and from the field-we provide a swinging arm, 25, which is pivoted to a lug, 26, on the under side of the feedslide, the forward end of said arm being adapted to register with and to wholly cover the apertures through said slide.

27 is a crank-arm extending from one side of the cut-off arm, and 28 a cord connecting the crank-arm with one of the handles or any suitable portion of the framework, so that the cut-off may be'readily operated by the.

person using the drill. WVe preferably provide a ring at the end of the cord adapted to engage a pin or hook, 29, upon one of the handles, as clearly shown in Fig. 1.

In order to insure that the cut-off arm'shall be always pressed tightly against the under side of the feed-slide when in the closed position, and, furthermore, to compensate for the slight changes in position of the feed-slide relatively to the hook on the handle with which the other end of the cord is engaged, weinterpose a coil-spring, 30, between the crank-arm and the hook. The closed position of the cutoff arm is clearly shown in Fig. 1 and the opened position in Fig. 5. The outer end of the cut-off arm should be weighted sufficiently to insure its dropping to the opened position the instant the cord is released from the hook upon the handle. The cord is passed through one or more eyes, 31, on the inner side of the handle, which prevent the ring from .dropping down out of the way.

WVhen from any cause it is necessary to stop the How of seed, the ring is pulled up and engaged with hook 29, the effect being to draw the cut-off arm up firmly against the under side of the feed-slide, thus cutting off the flow instantly.

- It will of course be understood that the various details of construction may be changed within reasonable limits without avoiding the principle of our invention.
